To aZZ whom it may concern Be it'known thatI, HARRIE A. BALLARD, of Somerville, in thecounty of Mid'dlesex and State of Massachusetts, have invented certain new and .useful- Improvements in I Loaders for Hand-Tackers, of which the following is a specification.

The present invention relates to an auto-u matic apparatus adapted to containtacks and to supply them in condition to be used in a hand tacking device. It is intended to p be used in connection with ajlasting machine, so that actuation of certainpartsof the latter will set the loader into operation forsupplying tacks to the tacking apparatus, which can be used to secure the edges of the upper after they are shaped over. the last by the wipers of the lasting machine.

The invention consists in a tack recepta cle which is mounted in connection witha' lasting machine, and is constructed so as to permit the insertion and removal of a pora tion of the raceway connected with a hand tacker, and has means'automatically set in operation by the movement'of certain of the lasting instrumentalities for supplying the tacks in regular order in the raceway of the tacker so that they can be automatically fed to and driven by the driving members of the latter.

The details of the invention are describedand. claimed in thejfollowing specification,

and illustrated in theaccompanying drawings, wherein V Figure 1 represents an elevation of a lasting machine having the preferred embodiment of my tack-loader connected therewith. Fig. 2 represents a rear elevation'of the forward part of the loader. Fig. 3 represents a sectional view of the loader, showingin elevationparts of a hand tackerdetachably connected therewith in position to receive tacks, that is, toI be loaded. Fig. 4 represents a detail elevation of the clearer by which tacks improperly placed on'the tacker raceway maybe removed. Fig. 5

represents a cross-section of the tacker race? wayon line 5-5 of Fig. '3', looking in the.

direction of the arrow. Fig. 6 represents an elevation of the loader. Fig.- 7 represents a section of the same on line 7,7 of Fig... 6.

Thetackd oader consistsqin a stationary receptacle niountedvupon a standardQ and having an opening 8:.through which tacks 3:

may :bemdropped into the interior thereof.

The rearflofthe receptacle 1 has an annularflange 4 .on which .is revolubly mounted: a

The latter is tack-holder and elevator 5. secured. to the end of a shaft 6 which extends through a bearing 7' at the top oi'a bracket Sconnected to the standard2. .On the shaft is secured a clutch member 9 having *peripheral inclined notchesqlO surrounded by'a loose sprocket or otherdriving wheel 1-1. In the notches 10 betweenrthe clutch; ,9 and driving/wheel are balls 12 Q adapted to be rolled up the inclined sidesof the notches and to be crowded thereby against the inner periphery of the driving wheel when the latter isturnedin left-hand rotation with respect to Figs. 1 and-8, the

.drivingwheel .11 being movable relatively 1- 1 Theloaderis adapted .tobe used inconnection-with a bed lasting machine ofany;-si1it-" able construction, such a one beingshown in Fig. 1, having a frame 13, supports 14 and 15 for a last holding ashoe upper 16, and

stretched andgcrimped over the bottom of i the last. Afterthe upper has 'thusj been shaped over the last, it1s necessary to secure the edges until; the sole ca'nbeapplie'd, and

8'5" I having alsolasting instrumentalities l7nand 18 by which the edges of the upper may be for that pur'po'seI use a hand tacking device, suchfas"is shown in F igi 8. 'Thehand tackerzis adapted to-be detachably engaged with the loader so that it canreceive the supply oftacks when not in'use,and="can be Ireadily disengaged when necessary, for placing tacks in' the lasted upper. In order"; that the tacker may beheldwhere it can be conveniently reached by the operator ofthe lasting machine lrmountfthe standard 2 of F the loader. on a support 19 secured-above the rear; portion of the lasting machine, and connect the tack-elevating device so that'it will be moved operatively when certain of the lasting instrumentalities are brought into active position.

The operating means consists of the driving sprocket 11 above described, a connecting chain 20, and a sprocket 21 on a shaft 22. The latter extends into the interior of the machine frame and carries a spur gear (not shown) meshing with a rack 23 on the carrlage 24 by which the lasting instrumentalities 17 are carried. It will be observed that when the carriage 24 is moved toward the last, the rack 23 turns the wheels 21 and 11 in left-hand rotation, causing connection of the clutch 9 to the wheel, and driving the As shown in Fig. 3, the tacker consists of a cylindrical body 27 in which operates a driving plunger 28, and is surrounded spirally by a tack raceway 29. The end 30' of the raceway is straight and tangentto the body 29. It is adapted to be inserted.

through a slot 31 in the stationary portion 1 of the loader. When inserted, it is detachablyheld by a latch 32 engaging a transverse bar 33 secured to a lag 34 which is fastened to the body 29. This latch is projected by a spring 35 surrounding the stem of the latch and bearing against a shoulder thereon at one end, and against a bushing 36 screwed into the frame of the loader. A

shoulder 37 limits the amount of projection of the latch. A beveled surface 38 adjacent the end of the latch on the side thereof opposite to the opening 31 enables the latch to be depressed by the transverse bar 33 when the raceway is inserted. A trigger 39 is pivoted at-40 to the frame of the loader, and has a slotted arm 41 engaging a pin 42on the latch. The trigger is mounted in close proximity to the tacker so that when it is desired toremove the. latter, the body thereof can be grasped by the hand of the operator, and the trigger pressed. by the forefinger of the same hand, whereby the tacker canbe released andv removed by a single motion of one hand. When the tacker is connected with the loader, its raceway end "30 extends a considerable distance ,into the interior of the loader at such an angle that gravity will cause the tacks to be fed therein. It liesdirectly under the lowest portion of the collector 26, which is formed. from a plate secured to the stationary partof the loader and projecting well within the inte- Iior of the elevator 5. It is arranged at an inclination substantially the same as that of the raceway end and has inclined plane sides forming a dihedral angle, the latter constituting a central depression in the collector.

A slot 43 is cut in the collector on the angle and is of such width that the points of the tacks may project through it, while their heads are supported by the sides thereof. As the tacks fall from the shelves 25, they are arrested by the collector and caused to slide toward the slot. The points of some of them enter the slots and are alined there by, while the others fall out and return into the elevator. Those which engage the slot are fed downward by gravity into the groove of the raceway.

' As shown in Figs. 2 and 5, the raceway consists of two plates 301 and 302, of which the inner side of the latter is partially cut OH to provide a tack groove 303. The plate 302'also has a flange 304 extending over the groove toprevent the tacks being thrown out of the latter when a blow is struck on the plunger 28. This covering flange terminates at the point 44 some distance below lowing correctly alined tacks from continuing down the raceway. Accordingly, to prevent the tacks from so lodging, I provide a clearer which consists of a number of arms 45 mounted on a hub 46 secured to a shaft 47. Slidingly mounted on the arms 45 are clogs or strikers 48 which partially embrace the arms and have ends 49 adapted to extend beyond the ends of the arms. These striker ends 49 are carried from right to left in engagement with the top of the raceway and dislodge the improperly placed tacks. the on the arms 45 enables the former to slide along the top of the cover flange 304 and drop below the end thereof. The strikers 48 are prevented from slipping off the ends of the arms by pins 50. On the shaft 47 of the clearer is a pinion 51 which meshes with an idler 52 driven by a circular series of radial teeth 53 on the forward side of the tack elevator 5. By this train of gearing, rotation of the elevator in the direction previously described, turns the clearer in right-hand rotation, as seen in Fig. 3. The collector 26 is detachably secured to the stationary receiver 1 of the loader and is provided at its sides with lugs 54 which are slotted at 55 to engage the shanks of screws 56 threaded into the casing. By means of these lugs and screws, the collector canbe quickly connected or disconnected and its The sliding engagement of the strik inclination can be adjusted. The screws 57 58 shown in Fig. 2 are adjustably mounted in the interior of the loader frame and project toward each other on opposite sides of the raceway. They are designed to center the latter so that the slot thereof will come directly below the slot 4L3 of the collector.

59 represents an integral shoulder formed on the frame of the tack-loader extending inward over the top of the slot 31. This shoulder acts as a stripper for removing the, tacks carried onthe raceway above the end.

44 of the raceway cover. If these tacks were not removed,they would be dislodged by thevibration of the tacker during ,its operation and lost. Consequently when the tacker is disconnected from theloader, it is turned slightly so as to elevate the rear portion of the raceway,',.and"the racewaypressed upward against the. shoulder .59;

Thereby the upper edge of the raceway slides in contact with the, stripper andYt-he tacks above the point aaiare engaged thereby and held back while the raceway is removed. These tacks thereupon drop and are guidedinto the holderoh The periphery of the tack-holderandele vator 5 is provided with spur teeth 60 WhlCll mesh with a pinion 61 on the shaft 62 of a wheel 63. This latter has a heavy rim and acts by momentum 'tocontinue the motion of the tack elevator after the driving impulse has ceased. Thus when the carriage 24 is moved inward and. an impulse is given to the driving wheel, the elevator 5. and wheel 63 are'set in motion, and owing to the momentum of the latter wheel, are continued in motion after the carriage has come to rest. This continued motion is permitted by the disconnectible clutch, and thereby the elevator is enabled to furnish an excess of tacks to insure that the tacker will be fully loaded. The fly wheel 63 is grooved externally to receive a belt whereby it may serve as the driver for the tack elevator when the latter is not directly connected to the lasting instrumentalities.

In order to prevent leakage of' the tacks through the slot 31 of the receptacle 1 when the tacker is removed therefrom, I provide the receptacle with a gate 6% which normally covers the slot. The gate is hinged upon a pin 65 (see Fig. 2) which is mounted in a base plate 66. The base is aflixed to the'in- 1. tack-loader having a casing, a tack lifting'device; said casing having an aperture for receiving theend of a tack-raceway in position to receive tacks fromthe lifter, a hand tacker to which said raceway is connected, and displaceable'means on said casing for engaging and retaining such raceway, said means being located so that it may 3 be engaged by a finger of the hand grasping said hand tacker.
